Parking ratio calculator

The parking ratio of a commercial property, on both conventions at once: spaces per 1,000 ft² of leasable area — the figure US tenants and lenders compare — and spaces per 100 m², the way the same car park is described in Europe. They are not interchangeable: 1,000 ft² is 92.903 m², so 4 spaces per 1,000 ft² is 4.31 per 100 m². Enter the spaces and the floor area in your own unit; both ratios and the area served by each space come out together.

The tool shows the initial payment, the maximum payment after the first adjustment (initial cap, bounded by the lifetime cap) and the worst-case payment at the lifetime ceiling — with an optional fixed-rate comparison.Cap rate calculatorCompute the capitalization rate of a rental property, and compare it with the market rate of your own comparable sales.Construction loan calculatorEstimate a construction-to-permanent loan in two phases. During the build you pay interest only on the funds drawn, so the calculator applies your rate to the average outstanding balance (which depends on the draw schedule). It then amortises the permanent mortgage that replaces the construction loan.

The Parking ratio calculator turns Number of parking spaces, Leasable building area (m²) into Parking ratio (spaces per 1,000 ft²), Parking ratio (spaces per 100 m²), Floor area served by each space, instantly and for free. For instance, with Number of parking spaces = 150 and Leasable building area (m²) = 3,700 it returns Parking ratio (spaces per 1,000 ft²) = 3.77, Parking ratio (spaces per 100 m²) = 4.05 and Floor area served by each space = 24.67 m².

How to use it

  1. Enter your values: Number of parking spaces, Leasable building area (m²).
  2. Read the result instantly: Parking ratio (spaces per 1,000 ft²), Parking ratio (spaces per 100 m²), Floor area served by each space.

Frequently asked questions

What does the Parking ratio calculator actually compute?

It takes Number of parking spaces and Leasable building area (m²) and derives Parking ratio (spaces per 1,000 ft²), Parking ratio (spaces per 100 m²) and Floor area served by each space from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

2 values: Number of parking spaces and Leasable building area (m²). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Number of parking spaces = 150 and Leasable building area (m²) = 3,700, the calculator returns Parking ratio (spaces per 1,000 ft²) = 3.77, Parking ratio (spaces per 100 m²) = 4.05 and Floor area served by each space = 24.67 m². Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Number of parking spaces = 300 and Leasable building area (m²) = 4,070 instead, Parking ratio (spaces per 1,000 ft²) goes from 3.77 to 6.85 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Number of parking spaces = 75 and Leasable building area (m²) = 3,330, Parking ratio (spaces per 1,000 ft²) comes out at 2.09. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Before making an offer: what the bank will lend, what the purchase costs on top of the price, and how much deposit closes the gap.

What is the most common mistake?

Budgeting for the price and forgetting the acquisition costs. Notary fees, transfer duty and registration add between 2% and 15% depending on the country — enough to sink an offer.

What is the difference between the Parking ratio calculator and the Price per square meter calculator?

This one returns Parking ratio (spaces per 1,000 ft²) and Parking ratio (spaces per 100 m²); the Price per square meter calculator returns Price per m² and Price per ft². That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Down payment calculator is the closest one after this: Work out your down payment, the loan it leaves, the cash you still have to find and the month you get there.

Where do the figures come from, and how current are they?

Fee scales and duty rates are published per country and per region, and they change with each finance act. Lending limits also depend on the bank's own policy, not only on the regulator's debt-to-income cap.
